MACHINE FOR SECURING METALLIC SCREW-CAPS T0 BOTTLES, JARS, AND THE LIKE.

Specification of Letters Patent.

Patented lDJec. T2, 19%.

Application filed January 27, 1915. Serial No. 4,620.

To all whom it may concern:

Be it known that I, FRED EVANS, a citizen of the United States, residing in the city of Summit, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Machines for Securing Metallic Screw-Caps to Bottles, Jars, and the like, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it pertains to make, construct, and use the same, reference being had to the accompanying drawings, and to numerals of reference marked thereon, forming a part of this specification.

This invention relates to machines for se-.

curing, preferably, metallic screw caps to the mouths of bottles, jars and the like, and consists of mechanisms whereby the act of securing is performed in a simple and efficient manner.

The objects of my invention are to increase the simplicity of the construction and operation of the machine, by decreasing the number of parts of which the usual machine is composed, by lessening or avoiding the necessity for adjustment of the various parts, and by increasing the convenience in manipulation of the machine. To this end, I have made many changes in this machine from similar machines described in previous patents, all with the object of increased efliciency.

The construction and operation 'of my machine will be more fully described in the specification which follows, and in the drawings which form a part thereof, wherein I have shown a preferred embodiment of my invention in a machine especially adapted for securing metallic screw caps to the mouths of bottles and the like.

Throughout the specification and drawings, like reference numerals are employed to indicate corresponding parts, and in the drawings, Figure 1 represents a side elevation of my improved machine embodying my invention. Fig. 2 represents a sectional elevation of the cup or socket for the reception ofthe screw cap; and Fig. 3 represents a fragmentary bottom plan view of the same.

In the drawings, 1 represents a suitable frame of any desired form or configuration, upon which is mounted an electric motor2, connected with a suitable source of electricity. Secured to one end of the motor shaft is a pinion 3, which meshes with a bevel-gear 4t secured in any convenient manner, preferably by means of a set screw 5, to the upper end of the cup-driving shaft 6, the lower end of which has screw-threaded engagement with the tubular extension of the cap-receiving cup 10. The cup-driving shaft 6 is mounted in a convenient bearing 7 formed on the front'end of the frame 1 of the machine, and a collar 8 secured to said shaft 6, by means of a set screw 9, limits the upward movement thereof.

10 represents a cone-shaped cap-receiving cup, provided with a tubular extension 11",

the upper end of which is screw-threaded, by means of which said cap-receiving cup 10 is rigidly secured to the lower end of the driving shaft 6. A bearing 12 is provided in the lower portion of said tubular eXtension to receive the stem 13 of the springactuated positioning element 14:.

A suitable head 17 is formed on one end of the stem 13, and interposed between said head 17 and the end of the driving shaft 6 is a spiral spring 16. The under side of the spring-actuated positioning element 14, which is secured to the stem 13 in any suitable manner, in its preferred form, has a recess provided with a lining 15, of felt,rubber, leather or the like, designed to engage with the top of the cap. j

The cone-shaped cap-receiving cup 10, is also provided with an interior lining 18 of felt, rubber, leather or the like, which may be secured thereto in any convenient or desired manner, and in its preferred form, this lining may be provided with suitable corrugations 19, designed to frictionally engage the screw-cap 20, so that when the cap is placed upon the mouth of the bottle 21, and the cap is in the position indicated in dotted lines in Fig. 2 of the drawings, the circumferential edge of the cap will have frictional engagement with the corrugated lining 19, and through the rotation of said cup, the cap will be screwed down tight upon the mouth of the bottle.

The operation of the machine is as follows: A screw cap of the type referred to, is, without any particular care, loosely placed upon the mouth of the bottle, jar or the like, to be capped," and the bottle is then moved upward in the direction indicated by the arrow in Fig. 1 of the drawings, while the cap-receiving cup is being rotated in the direction indicated by the arrow, until the upper surface of the cap engages withand is held against and propy Positioned, y being forced against the spring-actuated positioning element 14, thereby causing the circumferential edge of the cap to be frictionally engaged by the interior lining of felt, rubber, leather or the like of the cap-receiving cup, and by the rotation of said cap-receiving cup, the cap will be screwed down tight upon the mouth of the bottle.

It is not my intention to limit the inven tion to the precise details of construction shown in the accompanying drawings, itbeing apparent that such may be varied without departing from the spirit and Scope of the invention.

Having described the invention, what I desire to claim and have protected by Letters Patent, is:

-1. In a machine for capping bottles and the like, the combination of a hollow coneshaped rotatable cap-receiving cup designed to embrace a cap and secure it upon a bottle, a tubular extension formed on said capreceiving cup, a spring-actuated cap-positioning element designed to bear upon the top of the cap, one end of whichcap-posi- 'tioning element is located in said tubular extension, and the other end of which is located in thehollow coneshaped portion of said cup, a spiral spring located in said tubular extension, said cone-shaped cup being further provided on the inside thereof with a corrugated lining designed to bear upon and have frictional engagement with the circumferential edge of the cap to be operated upon.

2. In a machine for capping bottles and the like, the combination of a hollow coneshaped rotatable cap-receiving cup designed to embrace a cap and secure it upon a bottle, a tubular extension formed on the upper end of said cap-receiving cup, a headed spring-actuated cap-positioning element designed to bear against the top of the cap, the headed end of said cap-positioning ele ment being located in said tubular extension, and the other end of which is located in the hollow-cone-shaped portion of said cup, a spiral spring adapted to engage the upper surface of said headed cap-positioning element located in said tubular extension, said cone-shaped cup provided on the inside thereof with a corrugated lining, of semi-moisture impervious material designed to bear upon and have frictional engagement with the circumferential edge of the cap to be operated upon and means 101 opcrating said headed cap-positioning element and hollow cone-shaped cap-receiving cup.

This specification signed and witnessed this 19th day of January, 1915.
